In 2012, the City and County of Broomfield initiated a cost estimate and concept plan for meeting the project goal of having free-flow traffic lanes connecting the Northwest Parkway on the north to Jefferson Parkway on the south. The plan is called I-Fast.

In 2013, Jefferson County completed a preliminary study that included the development of the illustrative plan and a public input process that culminated in a formal survey. View the task order summary report of this work.
